SPARK-ARRESTER,

Specification of Letters Patent No. 2,496, dated March 18, 1842.

To all whom t may concern Be it known that I, JOHN V. L. IIoAG- LAND, ofJersey City, Hudson county, and State of New Jersey, have invented a newand Improved Spark-Catcher for Locomotive and other Steam-Engines; and Ido hereby declare that the following is a full and exact description.

The nature of my invention consists in carrying my funnel or chimney Aup through the outside casing B B B, and giving the top of the funnel abend or curve, so as to arrest the sparks in their' course, and directthem downward to the bottom E, E, by means of the concentric casing C,being of a semicircular form, attached to the front of the outsidecasing B, and concentric with the bend or curve of the top of thechimney or funnel A2, A2.

To enable others skilled in the art to make and use my invention I willproceed to describe its construction and operation.

I construct my funnel, orchimney,marked A, A. I then construct myoutside conical casing B, B, B for the purpose of holding the sparks. Ithen attach to the front of the outside casing, and placed concentricwith the our ves of the top of the funnel A2, A2 a semi- 'circnlarcasing marked C, C, C, for the purpose of giving the sparks a downwarddirection as 1s shown by the arrows in the drawing; by so altering thedirection of the sparks, they will strike against the chimney or funnelat the point D, which is a plate fastened to the funnel and bent at anangle so as to throw the sparks off easy from the chimney and not allowthem to cut the metal which they would do should the striking plate notbe placed there. Now the course of the sparks being changed from theirupward course to a direct downward course by the aforementioned bent topof the funnel A2, A2, in conjunction with the curve of the concentriccasing C, C, C, it will be readily seen that they will be carried belowthe influence of the draft or force of the exhaust steam, and drop bytheir own gravity to the bottom E, E, and rest there until taken outthrough the small opening F, F. Should there be any disposition with thelighter sparks to ascend, they will be immediately arrested bythe wirenetting covering the inverted to-p G, and thrown down through theaperture or hole H, II, which is so constructed as to throw the sparksbehind the back of the inside funnel and out of the influence of theexhaust steam, the whole forming a combination of arrangements for aspark catcher altogether new.

Vhat I claim as my invent-ion and desire Vto secure by Letters Patentis- The combination of the curved top of the funnel with the concentriccasing, placed in that or any other part of the chimney or funnel whichconstitutes the whole of my claim as is fully shown and set forth indrawings and specification.

J. V. L. HOAGLAND.
